Executive Summary: Key Legal and Evidentiary Issues

• Dispute centered on interpretation of the “Maximum Contract Amount” clause in a commercial Services Agreement.

• Applicants argued the clause guaranteed a minimum $2 million payment regardless of performance.

• Respondents maintained compensation was tied to acreage sprayed and capped at $2 million.

• Key legal issue involved applying modern principles of contractual interpretation from Sattva and Mosten.

• Extrinsic evidence offered by applicants was excluded for contradicting clear contract terms.

• Court concluded the payment cap was a ceiling, not a guaranteed floor, and dismissed the claim.

Background and contractual context

The applicants, Lloyd Good and West Central Air Holdings Ltd., operated an aerial spraying business. In 2013, they entered into an Asset Purchase Agreement and a related Services Agreement with the respondents—Precision West AG Corp. (operating as Provincial Airways and West Central Air (2013)), James Russell Wood, and James Pottage. Under the Services Agreement, the applicants continued spraying operations in the Rosetown area for a 10-year term. Their compensation was to be calculated on a per-acre basis: $1.50 per acre for the first 165,000 acres annually, and $2.00 per acre beyond that. The total payments were stated to be subject to a “Maximum Contract Amount” of $2 million, or a mutually agreed higher figure.

Nature of the dispute

Upon expiry of the agreement, the applicants claimed entitlement to the full $2 million, asserting the Maximum Contract Amount functioned as a guaranteed minimum. They relied on clause 1.01, the death-benefit clause (3.04), and a clause permitting cap adjustment (3.03), arguing these provisions collectively evidenced an intent to guarantee full payout regardless of the number of acres sprayed. The applicants also submitted extrinsic evidence, such as a non-binding proposal and financial documents, referencing the $2 million figure to support their interpretation.

Position of the respondents

The respondents countered that the Services Agreement unambiguously tied compensation to actual acreage sprayed, with clause 3.01 providing a clear per-acre payment structure. The total paid to date—approximately $1.475 million—reflected this calculation. They argued that the Maximum Contract Amount acted only as a cap and that the applicants never reached the required performance threshold to earn the full sum. They emphasized that clause 3.03 was designed to address in-season adjustments near the cap, not to establish a guaranteed minimum. Clause 3.04, they said, ensured the estate of Mr. Good received any earned but unpaid balance—not a full $2 million.

Court’s interpretation and decision

Justice R.S. Smith applied the leading principles of contractual interpretation from Sattva and Mosten, emphasizing the need to read the contract as a whole, relying on the plain language, commercial context, and grammatical meaning. The court rejected the applicants’ attempt to redefine a “Maximum Contract Amount” as a guaranteed entitlement. It held that if the parties had intended a fixed $2 million payment, they could have used language explicitly to that effect rather than a per-acre scheme. The extrinsic documents offered by the applicants were excluded from consideration, as they contradicted the contract’s text and had not been incorporated into the Services Agreement.

Final ruling and outcome

The court concluded that the “Maximum Contract Amount” clause established a cap, not a minimum guarantee. Compensation remained performance-based and was limited to the acreage actually sprayed. As the applicants had not reached the threshold to earn the full $2 million, their claim was dismissed. The court awarded costs to the respondents under Column 1 of the tariff.
